bye-over – n. the sheepish casual vibe between two people who’ve shred an emotional farewell but then unexpectedly have a little extra time together, wordlessly agreeing to pretend that they’ve already moved on.
I used to feel a bye-over was very awkward. I’d said goodbye, they had, and we’re delayed. I think the advent of Uber and similar services, where we wait more often on trips, has made it easier to say goodbye and then walk away a few steps to wait.
However, I would also say I’ve just learned to keep chatting with someone if there’s some delay, or even just come back and chat with others.
